SFECFICATION forming part of Letters Patent No. 428,668, dated. May 27,1890.

Application filed July 9, 1888. Serial No. 279,478. (No model.) Patentedin France April 24, 1886,N0.175,735; in England July 5, 1887, No. 9,525,and June 5, 1888, No. 8,213, and in Germany July 16, 1887, No. 43,871.

To all whom, it may concern:

Be it known that I, JULES DERRIEY, of Paris, France,have inventeclcertain new and useful Improvernents in Printing-Machines, (and whichhas been patented in France April 24, 1886, No. 175,735; in Germany July16, 1887, No. 43,871; in Great Britain July 5, 1887, No. 9,525, and June5, 1888, No. 8,2l3,) of which the following is a speciication.

This invention has reference to printingmachines of the kind generallycalled perfecting-machines, and more particularly to those known asAnglo-French perfecting-machines and its object is to overcome theobjections inherent in these Anglo-French machines, while retaining andincreasing the aclvantages obtainecl by the use of such machines. Theincrease of advantages is attained by constructing the machines so thatthey can be employed as clesired either as perfecting-machines or asdouble single cylinder machines, or as stop cylinder single machines, byreducin g the space occupied by the machines and by providing a betterarrangement for inking the forrns. The lifting movements which havealways existed in this class of machine for raising theimpression-cylinders are dispensecl with and so is the'usualrack-movement, and the speecl of the machine can thus be increased.

The accompanying clrawings illustrate the' inven tion.

Figure 1 represents a longitndinal vertical section of the machineembodying my invention; Fig. 2, a cletail vertical sectional viewillustrating the mechanism for moving and stopping theimpression-cylinclers; Fig 2% a detail view of the cam f'; Fig. 3, aplan of the machine, partly in section; Fig. 4, a longitudinal Verticalsection of the machine with the parts so adjusted as to change it into astopcylincler single machine; and Figs. 5 to 9, inclusive, show somemodified forms of a press embodying my invention.

Referring first to Sheets 1,*2, and 3, the machine is actuated by twolarge wheels A, connccted together by a crank-pin A". The niotion ofthis crank-pin is transmitted by a connecting-rocl to the Wheels B,which actuate the bed O of the machine, giving it a longitudinal traveldouble that of the wheels B.

Above the becl O are two impression-cylinclers D ancl E, held againstvertical movement, ancl the circumference of which is equal to thelength of the travel of the bed O. The oylinder D works when the beclmoves from right to left. It makes a complete revolution and then stops,it and cylinder E being reducecl in diameter at the proper point, asshown, and having their gear m utilated in the ordinary way. Thecylincler E works when the bed moves from left to right, likewise makinga complete revolution and then stopping. When the cylincler E isturning, the grippers with which it is provided take hold. of the whitesheet, which has been laid on the feedboard F, when they pass the end ofthis board and cai-ry the sheet to the line of the centers of the twocylinders. At this point the cylinder E stops, its grippers open byvirtue of the vibrating cam I', which is oaused to rise at this pointand release the sheet, and the grippers of the cylinder D at the sametime close upon it by reason of the vibrating cam I. As soon ascylinderD begins to move, itcar ries the sheet with it and ilnpresses itupon the form placed on the first half of the bed O. The cylinder Dmaking its complete revolution, again brings the sheet to the line ofthe centers of the two cylinclers. The grippers which held the sheet tothe cylincler D now open in their turn, While those on the cylinder Eclose and again take hold of the sheet. The cylinder E, again beginningto turn, carries the sheet with it and impresses it upon the form placedon the second half of the bed. The grippers open by virtue of cam I'when they pass the roller G, ancl the sheet is removed by tapes to thereceiving-boarcl H, While the grippers pass ou to take a new sheet, asbefore.

The foregoing is the action of the machine when it is employecl as aperfecting machine-that is to say, forprinting a sheet on its two siclessnccessively. When, on the other hand, it is desirecl to employ themachine 'as a single-cylinder machine, it is necessary to remove thevibrating cams I' ancl 1 which cause the grippers to open or close onthe line of the centers of the two cylinclers. The result is that thegrippers which have taken hold of the sheet at the end of the feed-boardF retain the sheet when the cylinder stops, and When the cylinder againbegins to move it carries the Sheet with it, so as to print it on oneside only, after which it delivers it from the machine at the roller G,as bcfore.

In addition to removing the vibrating eams I' and 1 a cam .1 isintroduced in connection with the cylinder D similar to the cam J'. Thiscam .P closes the grippers of the cylinder D to cause them to take holdof the white sheet as they pass the feed-heard F and opens them at theroller G after the cylinder 1) in its revolution has printed the sheeton one side. The sheets thns printed by means of the cylinderD areremoved by tapes to the receiving-board IF.

\Vhen set-off shcets are employed in ordinary machines, thcy areinserted by means of a Special feed-heard which eneumbers the npper partof the machine; but in my improved maehines when it is required to useset-off sheets, they are fed by means ol' the feettboartl so that muchmore of the npper part of the machine remains uncovered than in theordinary machincs which have aspecial feed-heard for the set-off sheets.

I will now proceed to describe the mochanism whereby theimpression-eylinders are put into motion and stopped. In the so-ealledAnglo-French maehines the eylinders re Volve eontinnonsly. The cylinderwhich has to print the sheet on the first side is lowered upon the bedof the machineby means of Special eeeentries, while the other eylinderislifted so as not to toneh the bed. Then when the bed travels in thereverso direction the first cylinder is lifled in its turn, while thesecond is lowcred. It will be readily understood that as soon as theparts which el'fect these lifting movements begin to wear there ceasesto be any acenracy in the impression. In the improved machine each ofthe cylin (leis is aetuated directly by the bed C by means of a raek R,placcd at the right of the bed for one of theeyli11lers,and gearing witha toothcd wheel or pinion T on the one cylinder and by means of a raekR', plaeed at the let't of the bed and similarly acting upon a toothetlwheel or pinion T' on the other cylimler. These raeks and pinions may beeither in the forms shown in Figs l and 3 or these shown in Figs. 5 towhere the racks R and R' are each composed of two parts *r and 7", andthe pinions T and T' are each eomposed of the two parts and t' of(liflferent radii, as and for the pnrpose to be deseribed farther on.The starting of the respective eylinders is etected by means 01:' camswhich aet upon levers K (Sheets 2 and 3) through the intermediation ot'eonneeting-rods. The lCVGl'S K have eaeh a Forked or toothed end whichstops the corresponding cylinder when it has completed its revolution,and holds it fixed nntil it has again to be put into motion. Thesestarting and stoppingactions are similar to those in what are known asstop-cylinder single machinesj and more partienlarly in these of Frenchand German Construction. The retention of the stop is assured by brakesL L, acting on pulleys L', and actuated by cams on the longitndinalshaft M.

A special eature of the improved machine is the combination of twocylinders like these in single stop-eylinder maehincs, the onc of whichstops when the other begins to move, and the stop ocenrring so that thegrippers which conduct the sheet are at the time of the stop on the lineof the centers of the two cylinders.

I will now explain the gripper movemcnts and the travel of the papel'.The gripper movemcnts will be best understood by reference to Sheet 2.They are eft'ectcd by fixed cams and movable gripper-ams. The fixcd eamscause the grippers to take hold of the sheet anl to deliver it after theimpression. The movable cams open and close the respective grippers, soas to cause the Sheet to be transferred from. the one eylinder to theother. Take, in the first place, the case of a sheet which has to beprinted on both sidcs without the intervention of a set-Oil' shcet. Thewhite sheet is laid on the fGOtLbOtl'd F against the feed-stops (L. Thegrippenlever b in revolving with the cylinder E rnns over the iixed camJ', and the ineline of this cam lowers the leyer, which, by means ofatoothed sector gearing with a pinion on the gripperred (7, eauses thisred to turn, together with the grippers, so that they close, take holdoi' the sheet, and carryit off. The grippcrsbring the sheet np to theline of the centers of the two eylinders and the eylinder stops. At thismoment the lever l) meets the movable grippercam I', which is liftcd bythe action of the camfand cansos the grippers to open. At the same timethe movable gripper-cam I is acted upon by means of theecccntricf',which is on the same shal't as the camsf. (The cam f' isshown detaehed in Fig. 2, so as not to confuso the drawings.) given tothe cam P cansos the grippcrs of the eylinder D to close, and thiscylinder begins to move immediately. These grippcrs draw the sheet withthem and make a com pletc turn, with the cylinder. 'J'heythereforcreturn to the startingpoint and the cylindcr stops. At this moment themovable cam 1 is lifted by the cam f', so that the grippers are opened,and simultaneonsly the movable cam 1', under the action of the cam f,closes the grippers of the cylinder E. This eylinder immetliately beginsto move and the sheet s carried on for the second imprcssion. \Vhenthese grippers come to the roller G, the lever which acts upon themriscs over the fixed cam J', which canses them to open and to releasethe shect, which is then carried to the receiving-board II by tapeswhich pass round the rollcr G and a rod g. \Vhen it is required to'inserta set off sheet, the action of the grip1'ers ispreeiselythesamegbutasecondlayenon lays the set-off sheet on the feed-board W up to the:feed-stops u and as soon as the grippers of the The movement thus.

cylinderD have passed the -upper part of the cylinder the rollers h arelowered on the cylinder and draw thesecond sheet, which is accom paniedby tapes, up to the rod Z. When it reaches this point, the set-off sheetis abandoned by the tapes and the rod Z is lifted by an eccentric placedon the brake-pulley of the cylinder D. At this moment the cylinder Dstops. Its grippers are opened and release the sheet which they carriedand on which the set-off sheet now lies. The grippers of cylinder Eclose. This cylinder begins to move, and draws the printed sheet, andwith it the overlying set-off sheet, which thus becomes interposedbetween the already-printed side and the cylinder E, after which thegrippers open at the roller G, and the sheets are delivered in themanner already explained.

When it is required to employthe machine as a double stop-cylindersingle machine, the cams I' 1 are removed and a fiXed cam J is fittedfor the cylinder D like the cam J' for. the cylinder E. In this caseeach cylinder takes its sheet at the feed-board and does not release itwhen the cylinder stops. After the stop the cylinder again begins tomove, prints its sheet on the one side, and-delivers it at the roller Gor G For inking the forms the inking apparatus em ployed is composed ofrollers, which are all of equal diameters,so that n practice any of therollers can be employed one for another. The vibrator Supplies the inkto an iron cylinder, which is in contact with both the Vibrator v andthe distributer. The cylinder is rotated by the rubbing contact of therollers, and is mounted on a fixed shaft cut with a screw having twocrossed threads, which causes the cylinder to receive a to-andfr0movement, so that the ink is distrbuted both on the Vibrator and thedistributer independently of the action of the distributer on thecylinder which is in contact with the inkers. The inking apparatus iscarried in a frame forming a sort of small inking-machin e, which can beslid into place on the frame of the printing-machine. This will allow ofits being moved out, if required, in order to facilitate corrections inthe forms placed in the machine.

In order to employ the machine as a single stop-cylinder machine, (seeSheet 4,) it is sufficient to disconnect the toothed wheel T, which isadj ustably fixed on one cylinder and gears with the rack R on themachine-bed, but leaving the wheel below the stop-lever of the cylinder,then to turn the cylinder so as to bring the grippers to the top of thecylinder at the time of the stop, instead of leav ing them placed on theline ofthe centers of the two cylinders, and to fix the wheel to thecylinder in this new position by means of bolts connecting the wheelwith the cylinder, it and the toothed wheel being provided with fourperforatons, each as shown at P, Fig. 4:

In order to -insure perfect inking of all the form, I arrange twoinking-rollers between the 'two impression-cylinders. These two rollers,which run over the whole form, produce uniformity between the partswhich receive more and those which receive less ink from the otherrollers.

The drawings represent a machine with flat ink-distribution; but it isevident that cylindrical ink-distribution can equally be adaptedthereto. Further, a point-rod A s added to the machine and is actuatedby a lever 13 fiXed on the shaft, which when the machine is used as aperfecting-machine serves for raising the lower part of the feed-board,so that the layer-on may adjust the sheet to the feed-stops. This verysimple transformation allows of the machine being used as either aperfecting-machine, with or Without a set-off sheet, as a doublesingle-cylinder machine, or as a stop-cylinder single machine, thusmaking it, so to speak, a universal machine, fulfilling all therequirements of a printing-office and rendering it particularly adaptedfor small establishments.

It will be understood that machines constructed according to this'invention should in principle have the circumference of the cylindersequal to the travel of the bed in one o direction and that the speed isthe more limited as the cylinder is larger. The stopping of the cylinderbecomes more diicult in proportion to the increase n its diameter, Whilethe bed, being driven directly by a crankmovement, caneasilybear anincreased speed. The large size of the cylinder, on the contrary, causesa difficulty in the movement of the stop-levei'. difficulty, Iconsiderably reduce the diameter of the cylinder by the followingarrangements, (see Figs. 5 and 6:) The cylinder need not have acircumferential travel exactly equal to the bed carrying the forms, asin the part where the contact eXists between' them for printing thesheet. I therefore place on the bed first a rack R, having a part 7gearing with a sector t on the cylinder in the part corresponding to thequarter-turn necessary to bring the head of the sheet in contact withthe bed and in the part corresponding to the duration of this contactfor theimpression' of the largest sheet for which the machine is made.The rest of the circumference is occupied by a sector. t', of largerradius, gearing with the part r' of the rack R, placed on the same sideof the bed underneath. The result is that in' this part of the inovementthe cylinder travels more slowly. These two arrangements allow ofreducing the Size of the cylin der and facilitate the action of thestop-levei'. The arrangement of the two racks and two sectors isrepeated at each side of the bed and on each cylinder.

Figs. 7, 8, and 9 represent a modified form of the arrangementsinvolving my invention wherein the production of the machine isincreased by utilizing each of the cylinders for printing two forms onthe obverse and reverse sides of the sheet, the sheet being cut in twoIn order to overcome this,

after the printing. The bed has at eaeh side a rack R, consisting of thetwo parts o and r', gearing with two sectors t and t' on eaeh eylinder,but placed in the order whiehis the reverse of the preeedingarrangement. The bed has a travel longer than the eirenmterenee of theeylinders and runs quicker than the eylinder turns in the part of theeylinder not allotted to printing. This printing part is equal to nearlythree-fourths of the eireumferenee of the eylinder. This partcorresponds to the total development of the two forms plaeed on the bed.\Vhen the first eylinder has printed this sheet corresponding to the twofOl'lllS, it comes to its stop on the line of the centers of the twoeylinders. The second eylinder takes this sheet and turns slowly untilthe sheet comes in contact with the bed, after which the eylnder turnsat the same speed as the bed and prints in its turn upon the two forms,the second form eoming upon the first that was previously printed. Thissheet is after-Ward delivered to the receiving-board, as has beenhereinbefore explained, by the Opening of the grippers in front of theroller G. These sheets are afterward cut in two, which donbles thenumber of eopies. This arrangement necessitates a given size of sheet,and the two ends of the forms should come at eaeh end of the travel ofthe bed at an equal distanee from the line of the centers of the twoeylinders.

The same machine ean be employed for any sizes of sheet smaller than thegiven size 'for whieh the machine is made by employing in this casesingle sheets eorresponding to one of the forms, the rednetion of thesize being made at the space whieh separates the two forms and thecylinders being provided with blanket only in the part of theireireumference corresponding with the form to be printed. \Vhen eaeh ofthe eylindcrs prints on the two forms, I place at eaeh end of the bed asmall fiat inking-table, reeeiving ink on the passage under theinking-rollers of the eylindrical inking arrangement and transferring itto two inking-rollers placed between the two eylinders and serving toink the end of the forms whieh in turn are not entirely inked by theeyli ndrieal inking arrangemen t. \Vhen a set-off sheet is necessary,this sheet is ted at the feed-board F, as has been already explained,and is drawn forward, as hereinbefore desoribed. The printed sheet andthe set-off sheet arrive at the same time at the exit-roller G, and atthis moment the first is sueked from below by a tube M and the seeondfrom above by a tube N, these tubes being connected with an air-pumpworked by the machine. This double suction separatcs the two sheets,eonipelling the set-off sheet to be taken hold of by tapes from therollers m n o, which eonduct it toa reeeiving device or ilier, While theprinted sheet falls on the reeeiving-board, where it is arranged byhand. The reeeiving device makes only a short movement and brings theset-off sheet to an inclined board of less length than the sheet whiehis thrown onto the board and hangs over it.
